Specification of Letters Patent.

Application filed February 19, 1913. fiorial No. 749,339.

To all whom it may concern:

Be it known that I, JULrUs W. KREILING, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Clutch Mechanism, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

My invention relates to clutch mechanism, and more particularly to aform thereof adapted for use in connection with the assembler belt ofa.linotype machine, such as is disclosed. for instance in Letters Patentof the United States to O. Mergenthaler, No. 436,532.

In the accompanying drawing I have 1 shown my invention in preferredform andby way of example, and as applied to the kind of machinementioned, but obviously many variations and alterations may be madetherein, and in its mode of application and use, which will still becomprised within its spirit.

Generally speaking, I desire it to be understood that I do not limitmyself to any specific form or embodiment, except. in so far as suchlimitations are specified in the claims.

In the drawing: Figure 1 is a front View of a portion of a linotypemachine, with my improvement embodied therein; Fig. 2

is a longitudinal section, on an enlarged scale, through the clutch,etc.; and Fig. 3

is a section taken substantially on the line 3'-3 in Fig. 2.

- The wheel or pulley A is actuated by any suitable driving means,comprising the rotating shaft B,the wheel being loosely mounted on theshaft, and my improved clutch devices being illustrated as employed inconnection therewith. The outer end of the shaft B is longitudinallybored or recessed as at C, and in the recess I dispose the cylindricalelement or rod D so as to permit its slight longitudinal movementtherein, the extent of this adjustment being controlled by theengagement of the inwardly projecting pin- B on the shaft B with theslot l) in the rod D. I-also provide the rod with detent devices,preferably in the form of a spring pressed ball E, to hold it in itsextreme positions in the recess CgQjThe outer end of the shaft B is alsoformedwith two pp t ly l ed notches G designed to re Patented Got. a,rare. I

by the rod D, the depth of the notches being sufiicient to permit thelongitudinal adjustment of the rod without disengaging the pintherefrom. Due to this constant connection, the rod D is caused torotate always in unison with the shaft B.

The wheel A is provided with the project- .ing hub H, mounted inproximity to the pin F, and formed at its ends with the two shoulders J,J. When the rod D is moved inwardly, the pin F is brought intoengagement with the said shoulders, and the wheel A is thus operativelyconnected to the shaft B. The outward movement of the rod, as indicatedby dotted lines in Fig. 2, breaks the clutch engagement. I

The coupling pin-F is preferably of cylindrical form and mounted in therod D, so as to be capable of an independent rotary movement about itsown axis. This feature adds durability to the construction andgcei gtainty to the operation. In cases where a' flat sided pin or the like isemploydd, its corners become worn, and the ditficulty of engaging 'itwith the hub H, as well as the;

liability to its accidental disengagement, are

both accentuated. With the rotatable cy lindrical pin F, new surfacesare being constantly presented, and the wear is thus distributed.Moreover, when the pin is pressed against the end of thehub,andbefo'reit engages with the shoulders J, because of its cylindricalshape, the friction is large. reduced, thus diminishing both the wear.and the liability to injury of the parts.

As previously stated, I have shtiwn my invention only in preferredformatn'd by way of example, and in a particular mode of application,but obviously many modifications and changes therein will suggestthemselves to those skilled in the art, without departure from itsscope.-

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is as follows: LThe clutch member comprising incombination two relatively-adjustable parts, one of said parts beingprovided with a transverse rotatably-mounted coupling pin. 2. The clutchmember comprising in combination two relatively-adjustable parts, one ofsaid parts being provided with a trans- Verse rotatably mountedcylindrical couloo pling pin, and the other part beingformed so asto beengaged a .113 The clutch m anism comprising in ciifiibinationtheidjustable element D providedggi t-lgthe. trans verserotatably-mountedCouplixiQ pin F,-- and the member A formed Wfll theshoulders J adapted to be engaged by said pin.

actuated by said pin. a

F carried by the element D and having. its

ends located in said notches, and the member A formed with the shouldersJ adapted to be engagedvby said pin.

In testimony whereof I afiix my signature in presence of two witnesses.{1
